Application filed April 28, 1910, Serial No. 558,240.

To all whom 'it may concern:

Be it known that we, Gnonon M. MILLER and SAMUEL R. SLAYMAKER, citizensof the United States, residing at Lancaster, in the county'ofLancasterand State of Pennsylvania, have invented certain new and usefulImprovements in Padlocks, of which the following is a specification,reference being had therein to the Iaccompanying drawing.

This invention relates to a self-locking padlock, and more particularlyto that class of padlock in which the shackle-locking mechanism isconstructed with a positive action and not a resilient action dependingupon springs. y

The objects of the invention are to so construct a lock of this typethat it shall embody a simple, positive and durable mechanism, composedof few parts, and proof against accidental opening caused by vjarrin.

l VITith these and other objects in view,.our

invent-ion consists in certainnovel construction andl combination ofparts as will be hereinafter fully described and claimedgand.illustrated inthe accompanying drawings, whic-h form a part 'of thisapplication, and in-whichlike figuresof reference .referftocorresponding parts in all of the views; but

it is fully understood that while we have herewith described ourinvention as shown, thatwedonot conneourselves to the-exact designpasfshown, as slight; changes ;may.. b,e, Inadewithin the scope oftlieclaims with?,

outdepartingirom thesp'irit of the in -v vention.

.Ia-Carryneout 01112- inventon, ,We emplea a. hook nosed shackle pivotedwithin ra case and-.normallyheld open. by an .actualiing spring, ahooked shackleengaging .dog

pivoted within the ,case andp rovide d with a projectlngstud, a seriesof key tumblers. for-engaging andi locking said dog, .akey actuated sliing unlockingyplate [for erigaging .the Astud of the dog-.and ,forcingthe dog out of engagement with the sha. ck le,and. a spring actuated,stop slideyl fon limiting the acties, .ef open position. In thedrawingsz-Figu-re 1, is 'La' front View of the lock, .Withf the` c oyerplate removed and showing the mechanism in a locked position. Fig. 2, isasimilar View,

the .dqgfwhenftheflock is in an but showing the position of themechanism when the look and the shackle are open. Fig. 3, is atransverse vertical sectional view through the center oit' the lock.Fig. 4, is a perspective view of the lock lremoved from the casing andseparated.

y The lock is constructed witha twopart casing, comprising the shell -orcase .1, hav.-

ing the sidewalls 2, which are cut away to admit the ends of theshackle, and the cover 3, which is retained by riveting the projjectingends of the, various studs and pins which project therethrough.

The shackle 4, is lformed with, the enlarged pivot end 5, which ismounted upon the pivot post .6, and normally held in an lopen positionby the actuating spring 7, which `is also mounted upon said post 6, withone of its ends engaging the side 8, l.

of a recessedvportion of said pivot end 5, and the other end of saidspring 7, engaged l byfa4 clip 9, vwhich is integral. with the case l'1; while the other .eI-1d of said-shackle 4, is for-med with the hookednose -10,and the shoulder stops 11, and 12, which abut l, against the.recesses 13, and 14, in the Acase wall 2, to prevent the, nose of theshackle 4, v-l rom'entering'too far into` the case 1'. t' Theshackle-engaging dogv 1 5, is; pivoted ,1 upon the pivot stud; 1.6',andis formed with the shackle-engaging hook; 1 7, the shackleInose-bearing surface 18, the catch point 19, thetumblenengaginglug120,and the stud 21, for engagement with the sliding locking plate.2 2. 1 1
